Hitting the āreset buttonā: The role of digital reorientation in successful turnarounds
Seismic shifts in industries brought about by radical technological innovations usually lead to a misalignment between the capabilities of many incumbent firms and the requisites of their new environment, and eventually, organizational decline. The current turnaround literature, while emphasizing operating and strategic responses to organizational decline that focus on efficiency and fine tuning product/market strategy respectively, ignores such organizational decline that requires fundamental reengineering of the whole firm and its value chain. This paper introduces the concept of digital reorientation as a long term turnaround strategy to respond to situations in which a firmās environment has been fundamentally restructured. Digital reorientation is a technology-enabled, simultaneous and multilevel change that transforms the organizationās core architecture and the way it serves its customers. We develop a framework to understand this turnaround strategy relative to traditional operational and strategic options and formulate propositions on internal and external contingencies that will likely influence the effectiveness of its implementation. Finally, using the newspaper publishing industry as an example of an environment that has undergone such disruptive change driven by digital technological innovations, we examine how the use of digital reorientation could help declining firms in that industry successfully turnaround their performance
Estimation of genetic parameters for preweaning and postweaning growth traits in the Gudali beef cattle using multiple trait derivative free restricted maximum likelihood
Records on pedigree information and growth traits of Gudali beef calves were obtained from the Institute of Agricultural Research for Development, Cameroon. Data were edited to have complete information on calf, sire and dam identity, sex, dates and season of birth, herd and weights at birth (BWT), 6 months (6 MWT), weaning (WWT), 12 months (12 MWT), yearling (YWT), 18 months (18 MWT), 24 months (24 MWT) and 36 months (36 MWT). Genetic parameters were estimated using multiple trait derivative free restricted maximum likelihood (MTDFRML) program. The estimated direct (h2a) and maternal (h2m) heritabilities for BWT, 6 MWT, WWT, YWT, 18 MWT, 24 MWT and 36 MWT obtained were 0.39, 0.10, 0.25, 0.21, 0.18, 0.25, 0.18 and 0.05, 0.07, 0.11, 0.10, 0.05, 0.09, 0.07, respectively. Estimates of maternal genetic variance and corresponding heritabilities (h2m) were lower than estimates for direct additive variance and heritability (h2a). The genetic correlation between direct and maternal influence were negative. The across-trait direct and maternal genetic correlation estimates were medium to high with the exception of BWT and 18 MWT; BWT and 36 MWT, had negative values. The positive values reported for the additive and maternal correlations between the growth parameters indicate that selection for one trait resulted in genetic improvement in the other. The moderate values of heritabilities indicate that selection for growth traits was effective.Key words: Covariance, heritability, genetic correlation, growth traits
Is laparoscopic surgery the answer to generalised purulent peritonitis from complicated appendicitis?
Aim
To compare the different outcomes in a single institution between patients with generalised
purulent peritonitis from complicated appendicitis diagnosed intraoperatively which were
managed laparoscopically to those managed via the open approach.
Methods
Data was collected from all cases admitted at Sebokeng Hospital over the past two years
(2008 & 2009) with an intraoperative diagnosis of generalised purulent peritonitis from
complicated appendicitis. Cases which were managed laparoscopically or by the open
approach were analysed.
The parameters analysed were the demographic findings, the theater duration, complications,
and days to the commencement of full ward diet, and length of hospital stay.
Results
During the study period, a total of 120 cases of appendicectomies with generalised purulent
peritonitis were performed. Of these, 58 cases underwent open appendicectomy (OA) and 62
cases had laparoscopic appendicectomy (LA). Both groups were comparable in the
demographics and preoperative findings.
The theater duration was significantly higher in the LA group (115.8 minutes for LA
compared to 86.7 minutes for OA. The rate of intraabdominal sepsis was also higher in the
LA group (12.9% for LA and 8.6% for OA). Both groups showed no statistical significant
difference between the wound sepsis or port site sepsis rate, the days to commencement of
full ward diet and length of hospital stay. More time was spent in ICU/HCU in the OA group
an average of 3.7 days as opposed to 2 days in the LA group.
However age, the duration of symptoms, the clinical presentation and the white blood cell
count (WBC) were influencing factors to the outcome of the OA group. Conclusion
Generalised purulent peritonitis from complicated appendicitis can be managed successfully
laparoscopically. Both approaches are feasible, safe and have comparable outcomes. Where
facilities are adequately skilled and resourced, the laparoscopic approach should be
considered the procedure of choice for complicated purulent appendicitis because it is less
influenced by preoperative findings and shows a trend towards less postoperative
complications
Is there a āDark Sideā to Monitoring? Board and Shareholder Monitoring Effects on M&A Performance Extremeness
Research summary: We investigate the effects of monitoring by boards of directors and institutional shareholders on merger and acquisition (M&A) performance extremeness using a sample of M&A deals from 1997 to 2006. Both governance research and legal reforms generally have espoused a āraise all boatsā view of monitoring. We instead investigate whether monitoring may serve as a double-edged sword that limits CEO discretion to undertake both value-destroying M&A deals and value-creating ones. Our findings indicate that the relationship between monitoring and M&A performance is more complex than previously believed. Rather than āraising all boatsā in a shift towards better M&A outcomes, monitoring instead is associated with lower M&A losses, but also with lower M&A gains
Trade of fish imported from Sub-Saharan Africa in the Cape Town Business district
Magister Philosophiae - MPhil (LAS) (Land and Agrarian Studies)Fish remains a vital source of food, income, nutrition and livelihoods for millions of people in
Africa. This study investigated the modalities of trading in fish imported from sub-Saharan
Africa into South Africa in the Cape Town Metropolitan area. The research analyses the
opportunities and constraints faced by retail fish traders and importers regarding the South
African and Southern African Development Community (SADC) policies that are in place, to
ascertain how far the policies go in facilitating the intra-regional fish trade. In addition, the
study analyses consumer factors underlying the attractiveness of imported fish, the channels
used for importation as well as the types and forms of fish imported into South Africa. The
study employs a qualitative approach using semi-structured interviews with purposively
selected key informant retailers, traders and City of Cape Town officials to collect the
information. Findings show that shop owners and traders face challenges in relation to
obtaining the required documents for trading, sanitary and phytosanitary certification and tariff
and non-tariff barriers at borders. Some of these challenges include long and tedious procedures
to acquire documents, as well as the limitations placed on the amount of goods traders can
import. Consumers (mostly from the diaspora) prefer the taste of fish that they are used to,
thereby creating an increasing demand for imported fish. National and regional policies put in
place do not facilitate the trade in fish as well as current municipal regulations for retailing
imported fish and other food types. The study also raises critical questions about the
implementation of sanitary and phytosanitary standards by officials in the food shops. The
thesis concludes that is it critical for national and regional policies to be coordinated and
harmonised for enhanced intra-regional fish trade, which could contribute towards increased
food security, nutrition and livelihoods
Carcass and organ characteristics of finishing broilers fed diets containing probiotics (Saccharomyces cerevisiae)
A five-week study was conducted to determine the effect of feeding varying levels of S. cerevisiae on carcass and organ characteristics of finishing broilers. One hundred and twenty 4-weeks old broilers of cobb strain were randomly assigned to four treatments (T1 = 0.6 g Saccharomyces cerevisiae (SC) kgā1 diet; T2 = 0.8 g SC kgā1 diet; T3 = 1.0 g SC kgā1 diet and T4 = 0.0 g SC kgā1 diet) with 30 birds per treatment and replicated twice with 15 birds per replicate in a completely randomized design. Feed and water were provided ad libitum to the birds in a deep litter system. In the end, data on growth, carcass and organ indices generated from the study were analyzed using one-way analysis of variance (ANOVA). Results showed no significant difference (p > 0.05) among the treatments in the birdsā growth performance indices. However, significant differences (p < 0.05) were observed in the birdsā values for liver weight, heart weight, shank length and thigh length with birds in T3 recording highest values of 61.30 g, 16.93 g and 12.00 cm for liver weight, heart weight and thigh length, respectively. It was thus concluded that finishing broilers fed 1.0 g of S. cerevisiae had superior carcass and organ characteristics than birds on the control and lower levels of inclusion

Capital assets: a community research intervention by the African Forum in Redbridge and Watham Forest
Duration: September 1999 - November 2000
This was a community-led initiative in which over 1000 Africans resident in Redbridge and Waltham Forest were asked about their assets and health needs. The survey was instigated by Redbridge & Waltham Forest African Forum, and undertaken by community groups themselves in collaboration with Sigma Research.
The survey was designed both to gather information from the communities and to provide information to them. The information sought was not simply about the participants needs but also about the assets within those communities to address those needs. The project sought information about the relationship between Africans living in Redbridge or Waltham Forest, their assets, health needs and the potential for interventions. It did so by:
providing all stakeholders with clear and accessible information about the demography of the local African communities.
mapping the priorities and needs of the groups.
assessing knowledge about HIV and its prevention.
mapping linguistic assets and social structures of participating community groups that may contribute to meeting these needs.
identifying acceptable, culturally appropriate methods of intervention.
Questionnaire content was led by the members of the African Forum as was the structure and content of the report. Members of community groups did all the interviewing. Between them, 41 interviewers talked to 1008 residents. The majority of African women and men living locally were at an age when people can be at their most active physically, mentally and economically. Mental health and HIV and AIDS were the major health concerns although health concerns were associated with country of birth. Many respondents lacked basic knowledge of HIV transmission. There is a need for more awareness of clinical sexual health services. Language ability and social networks are common assets for health. English is spoken by 78% of participants and 88% of the entire sample mentioned at least one person they were close to.
The survey provides information that helps to identify key areas where community organisations and statutory services working in partnership can improve quality of life and access to services.
The final report was called Capital assets: a community research intervention by The African Forum in Redbridge and Waltham Forest
