ObjectivesThe objective of this study was to evaluate the effects of pork hot carcass weight on loin quality and palatability of top loin chops.Materials and MethodsThe pigs in this study were raised to exceed standard market weights. Pork loins (N = 200) were collected from 4 different hot carcass weight groups: light (LT; less than 111.8 kg), medium-light (MLT; 111.8- 119.1 kg), medium-heavy (MHVY; 119.1- 124.4), and a heavy (HVY; 124.4 and greater). Prior to fabrication, purge loss percentage, instrumental color, subjective color and marbling, and pH were taken for each loin. Following fabrication, chops were assigned to fat and moisture analysis, Warner-Bratzler shear force (WBSF), consumer sensory analysis, or trained sensory analysis. For WBSF, consumer, and trained panels, chops were thawed for 24 h prior to analysis. Chops were cooked on clam-shell style grills and removed from the heat with the internal temperature rising to a peak internal temperature of 71°C. Consumers (N = 197) evaluated each sample for tenderness, juiciness, flavor like, and overall liking on 0 to 100 continuous line scales. Consumers were also able to indicate “yes” or “no” if the chop was acceptable for all palatability traits and overall. Trained panelists evaluated each sample for initial juiciness, sustained juiciness, myofibrillar tenderness, connective tissue amount, overall tenderness, pork flavor, and off flavor on similar 0 to 100 continuous line scales.ResultsLoins from all weight groups differed (P < 0.05) in weight (LT < MLT < MHVY < HVY). No carcass weight effects (P > 0.05) were found for loin instrumental color, subjective color, subjective marbling, purge loss percentage, pH, WBSF, moisture percentage, fat percentage, and drip loss. Carcass weight did not affect (P > 0.05) juiciness or flavor like ratings but did affect (P < 0.05) tenderness ratings and overall liking ratings. Chops from the HVY group were rated as more tender (P < 0.05) compared to chops from the LT weight group. Additionally, chops from the HVY weight group had greater (P < 0.05) consumer overall liking rating compared to chops from both the LT and MLT weight treatments. Hot carcass weight treatment did not contribute (P > 0.05) to the percentage of chops rated acceptable for flavor and overall liking. Chops from the HVY weight carcasses had the greatest (P < 0.05) percentage of chops rated acceptable for juiciness. Chops from LT carcasses had the lowest percentage of chops rated acceptable for tenderness. Trained sensory results also reflected tenderness and juiciness differences among carcass weight treatments. For both initial and sustained juiciness, chops from MHVY carcasses were rated as juicier (P < 0.05) compared to chops from both MLT and LT carcasses. Additionally, chops from the LT hot carcass weight treatment had the lowest (P < 0.05) myofibrillar tenderness ratings. Chops from MHVY and HVY carcasses were similar (P > 0.05) with greater (P < 0.05) overall tenderness ratings compared to chops from LT carcasses.ConclusionThese results indicate that as hot carcass weight increased, there were no negative effects on loin quality, and top loin chops from heavier weight carcasses had improved tenderness and juiciness compared to chops from lighter carcasses. This provides evidence that as the hot carcass weights of pigs in the United States continue to increase there will be no negative effects on quality and palatability.

Weight Groups

A total of 281 lamb carcasses covering three weight groups (18–22.9, 23–25.9 and 26–30 kg) and fatness (< 3 mm, 3–5 mm and > 5 mm) were used to determine the usefulness of several carcass measurements for predicting saleable meat yield. Carcasses were measured for fat and muscle depth, 3–4 cm from the mid-line between the 10th and 11th ribs, 12th and 13th ribs and immediately adjacent to the 13th rib using a Hennessey Grading Probe. This technique also determined total tissue depth at 11 cm from the mid-line between the 10th and 11th and 12th and 13th ribs. The depth of tissues over the 12th rib 11 cm from the mid-line was measured with a ruler. Carcasses were also visually assessed for muscle development (conformation score) on a 5-point scale (1 = thinly fleshed; 5 = thickly fleshed). All carcasses were fabricated into primal cuts which were trimmed to 5 mm of fat and deboned to provide an estimate of saleable meat yield. Ewe lamb carcasses had a higher proportion of kidney fat than wethers in all weight and fat groups (which ranged from 2.6 to 17.9 g kg−1 carcass weight). Saleable meat yield decreased as carcasses became fatter, whereas weight group had little influence on saleable meat yield within a fat group. Ewe lamb carcasses had lower saleable meat yields than wether lamb carcasses, mainly because of their higher amounts of kidney fat. A ruler measurement of tissue depth over the 12th rib combined with carcass conformation score provided the most precise prediction (R2 = 0 61; RSD 17.1) of saleable meat yield. It was concluded that a simple manual system based on these two measurements provided an adequate prediction of saleable meat yield. The accuracy of the procedure would be increased by excluding kidney fat from carcass weight for the prediction of saleable meat yield. Key words: Lamb, carcass, composition, probe, fat, grade

Abstract Beef carcass weights (HCW) and quality grades (QG) have increased in the United States the last 30 years, yet chilling systems have not drastically changed. The objective was to examine the influence of HCW and QG [USDA select, low choice (LC), upper 2/3 choice (UC), and prime)] on internal temperature decline of the chuck, loin, and round. Carcasses (n=309) were selected by weight [light (LW) = 295.5–341 kg; middle (MW) = 386.4–431.8 kg; heavy (HW) = 465.9–522.7 kg]. Data loggers were placed 20.32 cm deep in the chuck and round and 10.16 cm deep in the loin to record internal temperature for 26 h. Data were analyzed using the PROC MIXED procedure in SAS using HCW and QG as the main effects. A HCW×QG interaction was observed in the chuck (P=0.0286) and round (P&lt; 0.0001), but not the loin (P=0.0689). Chuck temperatures from LC HW carcasses were 1.8°C higher at 0 h compared to LC LW, LC MW, and select MW carcasses (P&lt; 0.05). At 26 h, all LW, select MW, and LC MW chucks had final temperatures at 6.1°C-7.7°C, followed by UC and prime MW at 9.1°C-9.5°C, then all HW chucks at 10.7°C-11.6°C (P&lt; 0.05). At 0 h, select and prime LW rounds had lower temperatures compared to other rounds (P&lt; 0.03). Round temperatures began to decline at 1.75 h in LW and 2.25 h in MW and HW carcasses. Final temperatures for LW and MW were 3.7-5.9⁰C and 1.6-3.0⁰C cooler, respectively, compared to HW rounds at 26 hr (P&lt; 0.04). Loins started with similar temperatures (39.2-40.7⁰C; P &gt;0.05). Elevated temperatures were observed in HW loins, compared to LW and MW loins (P&lt; 0.05), until 26 h when similar temperatures were achieved (P &gt;0.05). Carcass weight and quality grade interact during chilling and this relationship requires further research.

And Performance

Abstract. The positive effects of goal setting on motivation and performance are among the most established findings of industrial–organizational psychology. Accordingly, goal setting is a common management technique. Lately, however, potential negative effects of goal-setting, for example, on unethical behavior, are increasingly being discussed. This research replicates and extends a laboratory experiment conducted in the United States. In one of three goal conditions (do-your-best goals, consistently high goals, increasingly high goals), 101 participants worked on a search task in five rounds. Half of them (transparency yes/no) were informed at the outset about goal development. We did not find the expected effects on unethical behavior but medium-to-large effects on subjective variables: Perceived fairness of goals and goal commitment were least favorable in the increasing-goal condition, particularly in later goal rounds. Results indicate that when designing goal-setting interventions, organizations may consider potential undesirable long-term effects.

Methodological Considerations

Abstract. During the last decades, several studies have been conducted on the effectiveness of sexual abuse prevention programs implemented in different countries. In this article, we present a review of 70 studies (1981–2017) evaluating prevention programs, conducted mostly in the United States and Canada, although with a considerable presence also in other countries, such as New Zealand and the United Kingdom. The results of these studies, in general, are very promising and encourage us to continue this type of intervention, almost unanimously confirming its effectiveness. Prevention programs encourage children and adolescents to report the abuse experienced and they may help to reduce the trauma of sexual abuse if there are victims among the participants. We also found that some evaluations have not considered the possible negative effects of this type of programs in the event that they are applied inappropriately. Finally, we present some methodological considerations as critical analysis to this type of evaluations.

Using Data

Research has documented a number of acute and chronic stressors unique to the fire service. Due to the rise in mental health concerns in firefighters, there has been increased awareness of the negative effects of unmanaged stress. The present study employed a behavioral-analytic model to construct a brief screening measure of stress for this population: the Firefighter Assessment of Stress Test (FAST). Psychometric properties of the FAST were evaluated using data from active-duty firefighters throughout the United States. Results indicated the FAST has good internal reliability ( α = 0.89), as well as good convergent and discriminant validity. Also, the factor structure of the FAST revealed three significant subscales reflective of stress associated with responding to calls, administrative difficulties, and being overworked. Scoring and interpretation guidelines were established to suggest when further assessment is warranted. The FAST offers a brief and valid method of self-assessment of current stress levels in firefighters. Information obtained from the FAST (i.e., overall stress level and domains) has the potential to facilitate more immediate identification and recognition of stress in firefighters than what has been possible to date. Moreover, heightened awareness of stress and its effects will hopefully culminate in expanded efforts directed toward stress reduction and intervention for firefighters and their families.

Diagnostic Outcomes

A complete ultrasound examination (cUS) of the liver was performed on 172 female sheep and compared to the performance of a fast-focused ultrasound technique to diagnose echinococcal cysts. The scanned area was divided in: HYP (right hypocondrium), zone (Z)1 from HYP to the 11th intercostal space (IS), Z2 (10th–8th IS) and Z3 (7th–5th IS). Contiguous scans were also examined (HYP + Z1, Z1 + Z2, Z2 + Z3). Furthermore, during the procedures, the sheep were divided into three groups according to the body weight: Group (G) 1 (lighter), G2 (medium), and G3 (heavier). Finally, diagnostic outcomes were compared with necropsy findings. cUS obtained the highest values of sensitivity (Se) (91%), Specificity (Sp) (80%), and positive-zones (124/138, 90%), as compared to the other scans. cUS was also characterized by high values of Se and Sp and was able to identify a great number of positive-zones, when sheep were divided by body-weight groups. Similar performances were obtained in G1 by HYP (Se: 91%–Sp: 82%; 18/20, 90% of positive-zones) and HYP + Z1 scans (Se: 91%–Sp: 82; 90% of positive-zones, 18/20). Thus, in lighter breeds, the examination of HYP and HYP + Z1 scan windows could be considered reliable techniques for identifying the infected animals, while in heavier sheep the cUS still represents the best option.

Research on the psychological outcomes of physical education teachers’ perceptions of their work environments and variables that support adaptive coping processes is needed. Purpose: This study examined the relationships among role stress, emotional intelligence, emotional exhaustion (EE), and affective commitment among secondary physical educators in the United States (N = 246). Method: Using participants from a national database, variables were analyzed using multivariate analyses of covariances and structural modeling. Results: Urban teachers reported more role ambiguity than those working in other contexts. Role stress partially predicted emotional intelligence, whereas emotional intelligence predicted EE negatively and affective commitment positively. Role ambiguity influenced EE directly and indirectly through emotional intelligence. Role conflict and overload showed only direct relations. Conclusion: Emotional intelligence may buffer negative effects of role stress on EE while enhancing affective commitment by reappraising stress in manageable ways. Enhancing emotional intelligence may promote adaptive emotional responses.

As the number of women incarcerated in the United States continues to rise and their complex needs become more apparent, social workers must fortify their historical commitment to criminal justice reform. However, crafting more effective and compassionate responses to the needs of justice-involved women may very well require a more nuanced understanding of the holistic impact of incarceration on women’s well-being than the current literature offers. Utilizing the framework of feminist standpoint epistemology, the researcher engaged in qualitative content analysis to examine published personal accounts from 43 women to better understand their experiences in prisons and jails in the United States. Two overarching themes emerged from the analysis. First, the personal accounts illustrated that women experience prisons and jails as environments of denial insofar as these carceral environments deny women’s basic needs, their sense of humanity, and their personal power. The second overarching theme pertains to the holistic impact of the carceral environment upon women’s lives, meaning it has expansive effects on women’s biopsychosocial–spiritual functioning. Social workers should dedicate efforts to dramatically reducing the number of women behind bars and engaging in holistic intervention approaches that might counteract the negative effects of incarceration across domains of well-being.

The City

We use a simple theory of a system of cities to decompose the determinants of the city size distribution into three main components: efficiency, amenities, and frictions. Higher efficiency and better amenities lead to larger cities but also to greater frictions through congestion and other negative effects of agglomeration. Using data on MSAs in the United States, we estimate these city characteristics. Eliminating variation in any of them leads to large population reallocations, but modest welfare effects. We apply the same methodology to Chinese cities and find welfare effects that are many times larger than those in the US. (JEL H71, O18, P25, R11, R23, R41)

Immigrant Policies

Immigration and refugees are sets of global flows of people who are seeking information, technology, economic stability, and military, political, and social asylum. Immigrants and refugees, which is one of the categories of migrants, represent only one of many global exchanges in an increasingly independent world. As the number of immigrants increases, the national, demographic, and socio-economic composition of the foreign residents in a host country are impacted by the immigration and immigrant policies of the receiving country. Immigration is inseparably part of the American national identity and always will be, and the United States would not continue to grow without immigration. In setting immigration policy in the United States, policymakers must be sensitive to both the U.S. vulnerabilities and the effects of American policies on the countries of origin. Since the post 9/11 period in the United States, immigration, immigration policy and implementation have been debated issues. Especially after Donald Trump was elected, the debate about migrants and immigration issues has increased even more. The purpose of this study is to show the development of immigration in American history, the positive and negative effects of immigrants on American economy and social life, and the question of the effects of social inclusion policies on the immigrant problem.
